Series OST451 and OST451 SSG Thermal Storefront System

The Series OST451 Thermal Storefront System is engineered for optimal thermal performance and California Title 24 compliance. Offset glazing produces a flush appearance, while a slim 2" face trim and 4-1/2" depth offers a material cost advantage. The OST451 Storefront is a straight cut and stack system. No notching is required, which expedites installation and reduces labor.

Additional features include injection molded water deflectors, a continuous head and sill, and a top-load EPDM gasket that permits interior or exterior glazing. The available OST451 SSG model provides uninterrupted horizontal glass spans for a streamlined aesthetic.
